Healey won 58 per cent of the vote to finish ahead of John Allen, Steve Kenney and Bernard Gadney.
His name will go into the Walk of Legends on the approach to the new Caterpillar Stand at Welford Road, which opens next season.
Healey scored 61 tries in 248 appearances for Tigers after making his debut in the 1996/97 season. He retired from rugby at the end of the 2005/06 campaign having landed four Premiership titles, two Heineken Cups and the Pilkington Cup with Tigers. He also played 51 times for England and twice for the British Lions.
He said: To be voted into the Tigers' Legends team at scrum-half, where there were a lot of great candidates, is an honour.
The thing I remember most about Tigers was the spirit of the players. I had the chance to play with the likes of Martin Johnson, Darren Garforth, Graham Rowntree, Richard Cockerill I could go on naming players and in games where we had been up against it that spirit brought us through.
The game we were most up against it was the Heineken Cup Final in Paris. The spirit we developed over the years, against teams from Rotherham to Wasps, where we never gave up, held us in good stead. It's what I miss most about not playing rugby.
To be voted by the Tigers supporters is a great honour.
Voting has now turned to loose-head prop and fans can choose from a short-list of Robin Cowling, Roger Grove, Stuart Redfern and Graham Rowntree.
